Is lame servers an issue?

ok .ok. ok (I was about to say something else, but I think think I  
figured out where I was wrong in my previous post). Instead of saying  
"lame servers are sorta like the mail that you receive at your new  
home that are addressed to the previous home owner" would it be  
correct to say "lame servers are like the junk-mailers that have the  
wrong name on file for who lives at your new house (after all, it's  
the mailer that has the name on file, not the post office)?" From the  
perspective of Carlos and HIS server, someone out there thinks that  
his server has authority - but isn't - and since he doesn't, and it's  
someone else's misconfiguration, he can just ignore it (or send the  
logs to null). Or is this BACKWARDS? I've thought that a line in the  
log like what the OP was concerned about meant that MY server was  
asked directions, but are you saying that my server is the one doing  
the asking (and then so noting the lame server)?
